Stewart was placed on the 60-day disabled list Tuesday with a knee injury.
EDGE Analysis
Stewart's knee began acting up again, so the Pirates opted to give him the rest of the season off. The veteran catcher will end the season with a meager .214 batting average as Pittsburgh's backup catcher, which likely won't help him garner a larger role moving into next season. Jacob Stallings was called up from Triple-A Indianapolis to take his spot on the roster.
